Answer:
The answer is a. proteins
Answer: C. CO₂ and H₂O
Explanation:
Combustion reactions produce carbon dioxide and water.
Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.
